Re: is it possible to maintain a foreach directive after a VelocityEngine.evaluate()?

No, i don't think there's a way to do that automatically without
customizing your velocity build.  But you can fake it:

#set( $h = '#')
#set( $d = '$' )
#foreach( $element in $object1.elements )

#end
#if( !$object1 )
${h}foreach( ${d}element in $object1.elements )

${h}end
#end
